Amplified agricultural impacts from more frequent and intense sequential heat events Open
As the climate warms, interacting weather extremes such as sequential heat events pose complex risks to societies. Regarding global agriculture, laboratory experiments suggest that early crop exposure to heat may either confer tolerance or…

A Millennium of ENSO Influence on Jet Stream Driven Summer Climate Extremes Open
Summertime spatially compound climate extremes in the Northern Hemisphere are associated with dominant jet stream Rossby wavenumber patterns, including wavenumber5 (wave5). However, our knowledge of wave5, including its response to anthrop…

Jet stream controls on European climate and agriculture since 1300 CE Open
The jet stream is an important dynamic driver of climate variability in the Northern Hemisphere mid-latitudes. Modern variability in the position of summer jet stream latitude in the North Atlantic-European sector (EU JSL) promotes dipole …

A global compilation of diatom silica oxygen isotope records from lake sediment – trends and implications for climate reconstruction Open
Oxygen isotopes in biogenic silica (δ18OBSi) from lake sediments allow for quantitative reconstruction of past hydroclimate and proxy-model comparison in terrestrial environments. The signals of individual records have been attributed to d…

The Unprecedented Character of California's 20th Century Enhanced Hydroclimatic Variability in a 600‐Year Context Open
Recently, year‐to‐year swings in California winter precipitation extremes have resulted in drought, wildfires, and floods causing billions of dollars in damage. These recent precipitation swings represent an increasing trend in variability…

800 years of summer European-North Atlantic jet stream variability and its impact on climate extremes and human systems Open
<p>Climate extremes over the mid-latitudes are driven by a combination of thermodynamical and dynamical factors. In Europe, the primary dynamical driver of summer climate extremes is the position of the jet stream over the Europe-Nor…

Coupled impacts of sea ice variability and North Pacific atmospheric circulation on Holocene hydroclimate in Arctic Alaska Open
<p>Arctic Alaska lies at a climatological crossroads between the Arctic and North Pacific Oceans. The modern hydroclimate of the region is responding to rapidly diminishing sea ice driven in part by changes in heat flux from the Nort…

Reconstructing postglacial hydrologic and environmental change in the eastern Kenai Peninsula lowlands using proxy data and mass balance modeling Open
Despite extensive paleoenvironmental research on the postglacial history of the Kenai Peninsula, Alaska, uncertainties remain regarding the region's deglaciation, vegetation development, and past hydroclimate. To elucidate this complex env…

Coupled impacts of sea ice variability and North Pacific atmospheric circulation on Holocene hydroclimate in Arctic Alaska Open
Significance Our new record of hydroclimatic change over the past ∼10,000 years in Arctic Alaska reveals that periods of reduced sea ice result in isotopically heavier precipitation derived from proximal, Arctic moisture sources. This syst…
